Abstract: Two questionnaires were completed 1-2 weeks apart by 355 students in sixth through eighth grades, in seven randomly selected schools, to determine associations between the time spent playingvideogames each week, the types of videogames played, parental guidance of videogames, religiosity, physical aggression and state anger. Boys played significantly more videogames than girls as well as more violent videogames. Games with higher levels of violence were associated with increased physical aggression in the male population. State Anger was less strongly associated with videogameplaying. Videogameplaying generally predicted later aggression and anger better than current aggression and anger. When controlling for physical aggression and state anger at baseline, baseline play of the most violent category of games predicted follow-up physical aggression. Playinggames of any categories was a weak predictor of state anger. Four religiosity scales were developed: Intrinsic Religious Thought, Religious Activities, Intrinsic Religious Action and Extrinsic Religiosity. Students scoring high in intrinsic thought played videogames less and attended movies less. Parental guidance of videogames was positively related to intrinsic thought. High intrinsic thought religiosity also correlated negatively with both aggression scales and state anger. Parental guidance also had an effect on aggression though a complex one. Videogame play was less strongly related to physical aggression if students reported that their parents scored high in parental guidance. The total time spent playingvideogames correlated positively with reported physical aggression and state anger throughout the study and should be examined further.
